tunnel=building_passage conflicting definition

This page had the text "not to be confused with the combination tagging of highway=footway and tunnel=building_passage, which relates to a tunnel which begins at a point outside the building and ends at a point outside the building". However the part "a tunnel which begins at a point outside the building and ends at a point outside the building" clearly conflicts with the approved definition of building passage]].

Currently it is not clear if there is any meaningful distinction between highway=corridor and tunnel=building_passage however it would appear that a tunnel is a way "isolated" from the building whereas a corridor is just that - many door and other ways connecting it to other elements of the building.

I think your viewpoint is probably controversial: tunnel=building_passage has always been used for highways which are external to a building but which look absurd when rendered over the building. Anyone using this tag for indoor mapping is doing it incorrectly and vice versa. The only marginal cases I can think of is where the building passage if protected by doors, but in these cases they only connect with other ways which are not inside buildings.

The point is, the linked proposal and current definition describe exactly how to map tunnel=building_passage and this is in contradiction to the deleted text. What you are describing is some kind of mapping for the renderer edge case.
I am not a great friend of tunnel=building_passage, imo and by apparent intention of the author of the proposal it should have actually been covered=building_passage but was realized as tunnel ... you guess it .. as a mapping for the renderer hack. If I had some spare time I would propose covered=buidling_passage right now. RicoZ (talk) 15:05, 19 February 2017 (UTC)
The deleted text is alright when you replace "outside the building" with "on the outline of the building". However, the main difference between a highway=corridor and a tunnel=building_passage is certainly that a highway=corridor connects rooms or indoor facilities, while the purpose of a tunnel=building_passage is to connect outside ways and facilities. --Fkv (talk) 13:58, 29 May 2017 (UTC)

Only for pedestrians

Hello. If I understand correctly, this tag is only for pedestrian ways inside a building. Parking aisles inside covered parking lot for example should be tagged with highway=service, service=parking_aisle and indoor=yes. If I am correct, I think it would be good to make clear on this page that this tag is only for pedestrian ways inside a building. I also wonder whether this tag is useful, because we could tag corridors as highway=footway and indoor=yes, which would be consistent with the tagging of other indoor highways.

Inside of building questions

The definition of this tag says "to map a hallway inside of a building" which leads me to two questions:

  1. The "See Also" section refers to the covered=* tag "for ways outside of the building"--but isn't highway=corridor only for inside a building?
  2. It appears this tag should not be used for tunnels which connect buildings. Is this also the case for "skyways" (enclosed footbridges) that connect buildings?--Neuhausr (talk) 15:06, 15 March 2018 (UTC)
